自我职涯管理与职涯高原的关系

组织结构扁平化导致职涯高原员工逐渐增多,给个体和组织造成了消极影响。本研究通过对338名企业员工的问卷调查探讨自我职涯管理与职涯高原的关系。结果显示：自我职涯管理中的职业探索与层级高原、内容高原及中心化高原正相关;目标确定与层级高原、关注学习与内容高原、注重关系与中心化高原及内容高原负相关;自我展示虽在简单相关分析中与内容高原及中心化高原负相关,但在回归分析中则相关不显著。     

TWO-TO-ONE versus ONE-TO-ONE STUDENT-TEACHER RATIOS IN THE OPERANT VERBAL TRAINING OF RETARDED CHILDREN1

The operant training of two retarded children simultaneously on a picture-naming task was investigated as an alternative to the more commonly reported one-to-one student-teacher ratio. In Experiment I, two conditions were compared in which the children received primary reinforcement on a fixed-ratio schedule for responding correctly on prompt and probe trials in a standardized picture-naming procedure. During the “Group Condition”, the experimenter alternated from one child to the other after each primary reinforcement, after each incorrect response, after each response omission, and after each 10-sec period in which a child did not “attend” (by making a trial-initiating response) when it was his or her turn to be worked with. During the “Individual Condition”, the experimenter worked with only one child, and presented trials whenever the child made attending responses. Experiment I demonstrated that the Group Condition was more efficient than the Individual Condition in terms of total correct responses and total pictures learned per unit of training time. Incidental learning was also found in that the children learned some of each others' pictures as well as their own, thus indicating a further advantage of the larger student-teacher ratio. In Experiment II, an attempt was made to equate the two conditions, except for the presence of two children in the Group Condition, by ignoring the child in the Individual Condition for brief periods equal to those that occurred in the Group Condition when the experimenter presented training trials to the other child. The results demonstrated that the greater efficiency of the Group Condition was not due to the manner in which training time was allocated to the two members of a group. It also replicated the finding that the children learned some of each others' words in the Group Condition.     

行为决策研究的新取向——基于经验的决策

基于经验的决策是指,在统计概率情境中,个体通过重复选择与反馈获得选项的收益分布信息后进行的决策.基于经验的决策的研究范式主要包括探索-利用范式和探索→利用范式.其暗含的决策人假设是朴素直觉统计学家.其研究关注的主要内容是描述-经验的差异及其原因,以及基于经验的决策内部过程.未来的研究主要从描述-经验差异的原因、描述性决策范式下的结论的重新检验、基于经验的决策的解释模型及其应用研究等方面进行探讨.     

Evaluating a dual‐process model of risk: affect and cognition as determinants of risky choice

In three studies we addressed the impact of perceived risk and negative affect on risky choice. In Study 1, we tested a model that included both perceived risk and negative affect as predictors of risky choice. Study 2 and Study 3 replicated these findings and examined the impact of affective versus cognitive processing modes. In all the three studies, both perceived risk and negative affect were shown to be significant predictors of risky choice. Furthermore, Study 2 and Study 3 showed that an affective processing mode strengthened the relation between negative affect and risky choice and that a cognitive processing mode strengthened the relation between perceived risk and risky choice. Together, these findings show support for the idea of a dual‐process model of risky choice. Copyright © 2008 John Wiley & Sons, Ltd.     

Therapists' views of the relative benefits and pitfalls of group work and one-to-one counselling for bereavement

Aim: To explore therapists' perceptions of the relative benefits and pitfalls of group work and individual counselling for bereaved clients. Method: Semi-structured interviews with nine experienced bereavement therapists from a range of different contexts generated data which was analysed using grounded theory methodology. Findings: Groups were perceived as having a normalising influence, helping members make new social contacts and practice social skills. Individual counselling was seen as facilitating the initial telling of the story and the expression of extreme emotion. Discussion: The findings suggest that individual counselling may be useful as a primary intervention easing ‘emotional loneliness’ caused by the death of a spouse or attachment figure. Group work may be of more benefit later in the bereavement process, facilitating an engagement with the outside world and alleviating ‘social loneliness’. Implications for practice: This suggests that bereavement services might usefully combine group and individual provision. Initial assessment could help clients clarify their needs and facilitate their choice of service. This would be more cost effective and potentially ease clients' bereavement experience.     

外科临床决策的核心在精于选择

造就名医是个系统工程,理论和实践统一才有功底。为病人提供优质服务,要求医生有能力对病情进行综合分析思考、辨认、评估,对诊断、治疗进行鉴别,为选择科学的临床决策提供依据。理论与临床实践高水平的结合,难能可贵的是忌粗取精、忌浅求深、忌表识里,从临床汇集资料来思考、分析,最终做出选择,再到临床上去验证,从而得出正确的诊断和处理方案。善于选择和精于选择,是临床决策的核心,是临床医生综合素质走向成熟的产物,是一代名医成长的必然之路。     

How do investors make predictions? Insights from analogical reasoning research

Previous work on investor decision making has focused almost exclusively on information specific to the company being judged. Consequently, every decision is viewed as a novel event, disconnected from the investor's existing knowledge. In this study, the analogical reasoning literature provides the theoretical support for arguing that investors frequently utilize existing knowledge as a basis for generating predictions about a company's future. The specific proposal is that investors transfer their existing knowledge via two different forms of analogical reasoning. The first, relational reasoning, is based primarily on structural correspondence between a novel company and an existing schema. The second, literal similarity reasoning, is based primarily on surface correspondence of a novel company and a previously encountered company. Our theoretical framework is tested in a study in which experienced investors predict the outcome of a novel company's strategy after reading about the experiences of other companies who implemented a similar strategy. The results are consistent with the occurrence of both relational and literal similarity reasoning, with relational reasoning emerging as the dominant approach to generating investors' predictions.

自发性知觉经络反应中产生刺麻感和积极情绪的原因

自发性知觉经络反应(autonomous sensory meridian response,ASMR)是指在特定的视听刺激下,某些个体(ASMR敏感个体)在头皮后部、颈部乃至全身体验到一种令人极度愉快和放松的刺麻感的现象。其中,刺麻感的产生可能是个体大脑中负责感觉和肌肉运动的脑区高度激活引起的; 而与情绪和奖赏有关脑区的高度激活以及心率和呼吸频率的下降可能是产生愉快和放松感的重要原因。相比普通个体,ASMR敏感个体具有较高的神经质、共情特质、感觉受暗示性和特质正念。这可能说明ASMR敏感个体的感觉敏感性较高,情绪稳定性较弱,且比较关注自己身体的内外感受。这些个性特质可能导致ASMR敏感个体对某些视听刺激中所包含的一些感觉和情绪信息更加敏感,对其反应也更加强烈。目前,ASMR已经被用于抑郁,压力,失眠和慢性疼痛等的临床治疗以及商业广告之中。但ASMR可能会干扰个体的执行功能,在认知控制需求较高的情景下应尽量避免接触ASMR刺激。     

Dominance of texture over shape in facial identity processing is modulated by individual abilities

For face recognition, observers utilize both shape and texture information. Here, we investigated the relative diagnosticity of shape and texture for delayed matching of familiar and unfamiliar faces (Experiment 1) and identifying familiar and newly learned faces (Experiment 2). Within each familiarity condition, pairs of 3D‐captured faces were morphed selectively in either shape or texture in 20% steps, holding the respective other dimension constant. We also assessed participants’ individual face‐processing skills via the Bielefelder Famous Faces Test (BFFT), the Glasgow Face Matching Test, and the Cambridge Face Memory Test (CFMT). Using multilevel model analyses, we examined probabilities of same versus different responses (Experiment 1) and of original identity versus other/unknown identity responses (Experiment 2). Overall, texture was more diagnostic than shape for both delayed matching and identification, particularly so for familiar faces. On top of these overall effects, above‐average BFFT performance was associated with enhanced utilization of texture in both experiments. Furthermore, above‐average CFMT performance coincided with slightly reduced texture dominance in the delayed matching task (Experiment 1) and stronger sensitivity to morph‐based changes overall, that is irrespective of morph type, in the face identification task (Experiment 2). Our findings (1) show the disproportionate importance of texture information for processing familiar face identity and (2) provide further evidence that familiar and unfamiliar face identity perception are mediated by different underlying processes.     

组织中个体主动性行为“利与弊”
